As mentioned in my earlier post about XMLSerializer, the XML you get isn't perfect: element names come out ALL CAPS for some weird reason. And you get a bunch of automatic entity substitutions, most of which you probably want, others of which will simply break things if you try to deserialize the text back into a DOM later. (Forget about easy roundtripping.) But overall, it's a really useful trick.

I was hoping maybe this trick would also (as a free bonus) pretty-format any embedded scripts inside CDATA sections, but of course no such luck. In fact, due to automatic entity substitution, <![CDATA[ gets converted to &lt;![CDATA[, which is hilarious in a sad kind of way.
